=============

Finally the HadCRUT data for the whole of 2007 have been published.

As we have been told time and again that the world has been the warmest most recently, I have conducted a rank analysis on those values.

Three things of note for now:

(a) The year 2007 has been the coolest this century in most data sets, apart from Sea-Surface Northern Emisphere (second coolest) and Land Northern Emisphere (third warmest)

(b) In all data sets, there has been considerable cooling in November and December (and partly, in October 2007)

(c) Sea-surface Southern Emisphere temperatures in December 2007 have been the coolest since December 1995

There is more to the HadCRUT data and I shall return to this shortly.
